Inhibition activities of angiotensin converting enzyme and amino acid kefir whey profile of skim milk fermented by kefir grains

Abstract: Bioactive peptides fermented milk is very potential as functional food products for health. The aim of this study is to analyze the inhibition activity of Angiotensin Converting Enzyme and kefir whey amino acid profile and IC50. The design being applied is a comprehensive random design with five treatments (fermentation time 0, 3, 6, 9 and 12 days) and 3 replications. ACE inhibition indicators include ACE inhibition with IC50, protein, peptide concentration, total proteolytic, and amino acid profiles. The resu… Show more

“…After analyzing with ANOVA, it turns out that the treatment has a very significant effect on the water content value of fermented cob (Lindawati et al, 2018). The highest water content value was obtained in treatment B (72,517) followed by Treatment C (71,781) and the smallest was treatment A (71,368) and from the Notation treatment, A and C had the same notation.…”

“…Bakteri asam laktat (Lactobacillus) optimum bekerja pada pH 5, 8-6,6 (Ballows et al, 1991). Kadar lemak yang diperoleh dalam penelitian ini sama dengan hasil kadar lemak kefir whey yang dilaporkan Lindawati et al (2018) berdasarkan waktu penyimpanan tidak berbeda nyata (P>0,05).…”

“…Proses fermentasi kefir oleh bakteri asam laktat menghasilkan asam, yang kemudian asam tersebut akan mengkoagulasi protein sisa. Hal ini sesuai dengan hasil penelitian Lindawati et al (2018) bahwa selama proses fermentasi susu, kondisi asam menyebabkan peningkatan aktivitas Lacto-bacillus bulgaricus dengan enzim proteolitiknya dalam membiodegradasi protein. Kadar protein yang diperoleh dalam penelitian ini lebih tinggi dari hasil penelitian Tohari (2012) melaporkan bahwa kadar protein kefir susu kambing 4,42-4,54%.…”

“…Hal ini diduga disebabkan selama proses fermentasi kondisi asam menyebabkan terjadi peningkatan pertumbuhan Lactobacillus sp dan aktivitas enzim proteolitik bakteri asam laktat. Hal ini sesuai dengan penelitian Lindawati et al (2018) melaporkan bahwa dalam penelitiannya selama proses fermentasi susu, kondisi asam menyebabkan peningkatan aktivitas Lactobacillus sp dengan enzim proteolitiknya dalam membiodegradasi protein. Kondisi asam disebabkan oleh aktivitas biodegradasi laktosa susu oleh bakteri asam laktat sehingga menghasilkan asam laktat.…”
